rllhe present invention relates to a manuacturing process of guide members for the balls, rollers and the like.

The main object of the invention is to provide a manufacturing process enabling l5 vided with radially extending notches orI uide members to be economically obtained rom the triple point of view of material, labor and tools.

To this eiiect sheets of suitable material and width are provided with series or sets of aligned holes and rolled up in tubular form. Sections or rings are taken from the said tubes, said sections or rings having each time one of their circular side faces prohousings :tor the balls, rollers and the lilre By way of example; the annexed drawing l"shows the successive steps of manufacturing a ball cage according to the process of .0 the invention.

with the joint of each ring, and the notches,

in proper relative position;

Fig. 6 is a perspective view of a cage, provided with lateral holes.

Plane sheets (Fig. l), of appropriate section, and of a width equal or practically equal to the developed lengthof the cage to c be formed, and for example of brass, iron or steel etc., are punched with series or sets of aligned holes b (Fig. 2), such holes being 'of oblong form in the example considered. The sheets thus punched are rolled up and expanded into cylindrical bodies or tubes as seen in Fig. 3. By cutting the tubes so formed, along the dotted lines of Fig. 3, rings are obtained, the edges of which are latand provided with semicircular notches, respectively.

These rings. coupled together by their notched edges adjacent, and the notches opposite each other (Fig. 5), are -maintained in such osition for the boring of lateral holes a Fig. 6), said holes being used for the final assembly of the two rings or conjugate halves constituting the cage.

It will be understood that the joint-between the ends of the sheet forming eac of the tubes may be welded before cutting .he rings withoutdeparting from the scope of the invention.

I claim: l

1. A process of manufacturing guide members for the balls, rollers and the like in ball or roller bearings which consists in cutting sheets of suitable raw material to a width approximately equal to the circum-- ferential length of the desired guide members; punching. in the said sheets series or setsv of aligned holes; rolling up` and eX- panding the sheets in the form of tubes, cutting the tubes along parallel lines passing through the holes and between the series off. holes, in order to form guide and spacing rings for the balls, rollers and the like.

2. A manufacturing process according to claim 1 characterized by the fact that the rings obtained from the formed tubes are coupled together by pairs in order to torni cages for balls, rollers and the like.
